301 redirect puzzle

["Edd Dawson" <edd.dawson@xxxxxxxxx>]

I have a bit of a 301 puzzle here that I can't quite solve, and maybe someone can help me out.

I have 3 pages:

page 1=  /merchant.php?i=1
page 2=  /merchant.php?i=1&j=2
page 3=  /merchant.php?=1&j=2

I want to us a combination of url-rewriting and 301 redirects so they so a request to the old page url's are forwarded to:

page 1= /merchantname
page 2= /merchantnameproductname1
page 3= /merchantnameproductname2

and when these new url's are reached they actually are generated behind the scenes by the old urls.

Now I thought I had it with the following code in my Apache config:

   RewriteRule ^/merchantnameproductname2 /merchant\.php\?i\=1\&j\=2 [PT,QSA,NS,NE]
   RewriteCond %{REQUEST_URI} ^(.*)merchant\.php(.*)$
   RewriteCond %{QUERY_STRING} ^i\=1\&j\=2$
   RewriteRule ^(.*)$ /merchantnameproductname2? [R=301,L]

   RewriteRule ^/merchantnameproductname1 /merchant\.php\?i\=1\&j\=1 [PT,QSA,NS,NE]
   RewriteCond %{REQUEST_URI} ^(.*)merchant\.php(.*)$
   RewriteCond %{QUERY_STRING} ^i\=1\&j\=1$
   RewriteRule ^(.*)$ /merchantnameproductname1? [R=301,L]



   RewriteRule ^/merchantname /merchant\.php\?i\=66 [PT,QSA,NS,NE]
   RewriteCond %{REQUEST_URI} ^(.*)merchant\.php(.*)$
   RewriteCond %{QUERY_STRING} ^i\=1$
   RewriteRule ^(.*)$ /merchantname? [R=301,L]


Now what happens is that the rewrite and 301 redirect works for page1,
but page2 and page3 the 301 works and I get directed to the correct new
page url, but the underlying rewrite always creates the content for
page2, never page3

I am a bit stuck.. can anyone see the flaw?

Thanks.
